  • Heat and mass transfer of micropolar fluid flow over a stretching sheet by legendre collocation method

    Heat and mass transfer of micropolar fluid flow over a stretching sheet by legendre collocation method

    Mathematical modeling is more explicitly tied to some physical assumptions as exhibited in Fig. 1. It contemplates a steady, laminar, free convection, and incompressible flow of a micropolar fluid above an expandable sheet \(\:\left(y=0\right)\)

    How to avoid nuclear war in an era of AI and misinformation

    The Doomsday Clock — a symbolic arbiter of how close humanity is to annihilating itself — now sits at 89 seconds to midnight, nearer than it has ever been to signalling our species’ point of no return.

    Many threats, including climate change…
